Abstract: 1176.003 S P E C I F I C A T I O N          FEED TUBE PROTECTOR FOR A FOOD PROCESSOR               INVENTOR: JAMES E. WILLIAMS     ABSTRACT OF THE DISCLOSURE          A feed tube protector is provided for a food processor of the type having a housing enclosing a motor, a working bowl which is detachably mountable on the housing with a motor-driven shaft in the bowl for receiving various rotatable food processing tools which are removably installed on the shaft, and with a removable cover positioned on the bowl during operation of the machine.  Food processors of this type normally include a feed tube which is carried by the cover, and a manually operated food pusher or plunger which is used to feed food items down through the feed tube to the rotating food processing tool.  The feed tube pro-tector has an outer sleeve carrying a manually operable actuator for enabling motor operation only when the outer sleeve is properly positioned in place over the feed tube, and this outer sleeve is associated with a movable food pusher mounted for movement within the interior of the outer sleeve.  When the cover is properly positioned on the bowl and the outer sleeve is mounted over the feed tube with the food pusher being positioned and manually movable within the passageway in the feed tube, the actuator means carried by the sleeve is operatively associated in enabling relation-ship with control means in the housing to permit operation of the motor drive for the food processor. Thus, inadvertent insertion of a hand or a foreign object through the feed tube into the bowl is prevented when the rotatable tool is being driven by the motor drive.  By virtue of this arrange-ment, the feed tube can safely be shortened, if desired, and made to have a larger cross-sectional area than in UL-approved food processors which are commercially available today in the United States for home use so that larger food items can be inserted whole through the feed tube into the food processor as well as allowing the placing of elongated food items horizontally in the feed tube so that they can be sliced longitudinally.  Moreover, utilizing the feed tube protector in accordance with the present invention permits the entire size of the working bowl, cover and feed tube to be proportionally enlarged for providing a larger overall machine without compromising the safety features now provided by the relatively tall and narrow feed tube in prior art machines.

Abstract: Abstract of the Disclosure An improved method and apparatus senses the extent of actual wear of a grinding wheel at an area where the wear will be the greatest during the grinding of a workpiece.          The grinding wheel is dressed by removing material from the grinding wheel to an extent which is a function of the extent of sensed wear at the location where the wear is the greatest.  The apparatus includes a probe member which is movable toward the circular working surface or side of the grinding wheel from a retracted position and a detector assembly which detects when the probe member initially engages the circular side of the grinding wheel.  In some embodiments of the invention, the probe member is moved toward the grinding wheel in incremental steps with sufficient time between the steps to enable the grinding wheel to rotate through slightly more than one complete revolution.  In one embodiment of the invention the detector assembly includes a mass which is connected with a probe member.  Upon initial engagement of the probe member with the circular side of the grinding wheel, relative acceleration occurs between the mass and probe member.  In another embodiment of the invention the detector assembly includes a load cell which detects the occurrence of deflection upon initial engagement of the :                        -2-probe member with the grinding wheel.  In still another embodiment of the invention, the probe member is moved with a wheel dressing tool to detect when a wheel dressing operation has been completed.  After a wheel dressing operation has been completed the rotational speed of the grinding wheel is increased to maintain a desired surface speed even though the diameter of the grinding wheel has decreased.

Abstract: ABSTRACT OF THE DISCLOSURE There is disclosed a security type hinge construction comprised of a pair of hinge leaves each having at least one adjacent knuckle and adapted for attachment to a door or door frame, or the like for accommodating pivo-tal movement therebetween.  An electrical circuit component such as a switch is carried by one of the knuckles in a fixed orientation and operating means for the component is carried by the other of the knuckles, such that the re-lative pivotal movement of the hinge leaves can be employed to actuate or operate the component.  As such, the component can be wired in circuit to provide an indication of a change in the relative orientation of the hinge leaves, which correspondingly indicates a change in the position of the associated door with respect to its door frame.  The electrical circuit com-ponent or switch is further sealed within its associated knuckle, so as to substantially preclude intrusion of moisture or the like, without regard for the orientation or mounting position of the hinge construction, which moisture if entering the hinge bore could result in short circuiting of the circuit component, thus negating the monitoring effect of the assembly.
